Abstract: PROBLEM TO BE SOLVED: To make visible light rays and exciting light rays incident on a light guide with low loss. SOLUTION: Plural sectorial selective transmission members 272 which constitute a disk as a whole project to a flat pyramidal shape when the segment of the pivot of a folding fan thereof is pressed by a transmission member 273. The visible light rays (parallel light beams) past a shutter 24 transmit the selective transmission members 272 and head as the parallel light beams toward a condenser lens 28. The exciting light rays (parallel light beams) past a shutter 26 are reflected by the exciting light reflecting films of the selective transmission members 272 and are headed toward the condenser lens 28. However the selective transmission members 272 project to the shape equal to the shape on the flanks of the pyramid and therefore the reflected exciting light are made incident on the condenser lens 28 while the light rays are slightly diffused.  The exciting light rays are made incident as diffusing light rays on the condenser lens 28 and are converged at the incident surface of the light guide 13 in the same manneer as with the visible light rays by the influence of the axial chromatic aberrations of the condenser lens 28.
